The hollow vitrified micro bubbles heat preservation and insulation composite material has the advantages of good heat preservation, heat insulation, fire prevention and construction properties, is insusceptible to the biting of insects and ants, and is economical and environment-friendly.
Description
Technical field
The present invention relates to building material technical field, more particularly relate to the heat preserving and insulating material of body of wall.
Background technology
At present, from the main insulating material of existing structure body of wall, glass wool generally commonly used, polystyrene foam plate and urethane foam-in-place plate etc.Adopting the wall thermal insulation structure of polystyrene foam plate is basic unit's metope, binding agent, polystyrene foam plate, reinforced grid cloth, priming paint, putty, finish coat.Polyurethane coating External Walls Heating Insulation structure is basic unit's body of wall, polyurethane primer, polyurethane insulation coating, front mortar, lightweight leveling layer, anticracking grout composite gridding cloth, putty, exterior coating.The glass wool material exists construction trouble, the problem of heat-insulating property difference.There are the construction technology complexity in polystyrene foam plate and urethane foam-in-place plate, and wall weight is big, and cystose easily comes off, and easily shrink, and defective such as easily light.Hollow glass micropearl (hollow glass microbead) is a kind of small, the spherical shape powder of hollow.Particle diameter can be selected arbitrarily between the 1-500 micron as required, and density is at 0.1-0.3g/cm
3Have that volume in light weight is big, thermal conductivity is low, ultimate compression strength is high, the advantage of dispersed, mobile, good stability.In addition, also have insulation, self-lubricating, sound insulation, do not absorb water, fire-resistant, corrosion-resistant, radioprotective, excellent properties such as nontoxic.For this reason, how to utilize glass bead exploitation heat preserving and insulating material to become passable that people are inquiring into.
Summary of the invention
Purpose of the present invention is exactly that a kind of not only thermal and insulating performance that provides for the deficiency that solves prior art is good, fire-retardant, high temperature resistant, and the hollow vitrified micro bubbles heat preservation and insulation composite material that adhesive power is strong, ultimate compression strength is high.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of hollow vitrified micro bubbles heat preservation and insulation composite material, comprise glass bead and gelling material, glass bead is as the aglite of mixed mortar, admix among the gelling material, it is characterized in that, the content of described glass bead and gelling material is respectively: glass bead 20-50 part, gelling material 40-55 part; Described gelling material is the mixture of cement, sand, whipping agent and water-resisting agent, cement 40-60 part, and sand 2.5-3.3 part, whipping agent and water-resisting agent are an amount of.
As further specifying of such scheme, the size range of described glass bead is 0.5-1.5mm; Described glass bead thermal conductivity be 0.028-0.05w/m.k; The accumulation unit weight of described glass bead is 50-200kg/m
3Described for the refractoriness of glass bead be 1208-1360 ℃.
Described sand is natural river sand or quartz sand.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
1, the present invention adopts glass bead except that having light weight, insulation, thermal insulation, fp excellent properties, also have do not burn, intensity height, water-intake rate are low, the advantage of long service life; Because glass bead is irregular spherical particle, and its inside is the porous air cavity configuration, and surperficial vitreous is sealed, and gloss is level and smooth, and physicochemical property is very stable.
2, the cylindrical compress strength of glass bead is higher, and therefore, intensity morning of this mortar is very high, helps construction, the reduction of erection time, increases the benefit.
3, thermal conductivity is little, because of the thermal conductivity of glass bead itself at 0.028-0.05w/m.k, therefore, be suitable as very much the material of building heat preservation.
4, construction technology is simple, with ordinary mortar constructional method basically identical, need not the insulated curing time of traditional thermal insulation mortar, and the duration is short, saves cost.
Embodiment
Hollow vitrified micro bubbles heat preservation and insulation composite material of the present invention comprises glass bead and gelling material, and this gelling material is the mixture of cement, sand, whipping agent and water-resisting agent; wherein; sand is natural river sand or quartz sand, and glass bead is admixed among the gelling material as the aglite of mixed mortar.Each amount of substance that the present embodiment matrix material is comprised is respectively: glass bead 43kg, and cement 53kg, 3.05 parts in sand, whipping agent and water-resisting agent are an amount of.The physical index of described glass bead is:
| Performance | Unit | Index |
| Granularity | Mm | 0.5-1.5 |
| Unit weight | Kg/m 3 | 50-200 |
| Thermal conductivity | w/m.k | 0.028-0.05 |
| Cylindrical compress strength | The vacuum filtration method is measured % | 20-50 |
| Balling ratio | The VOLUME LOSS % of 1Mpa pressure | 38-46 |
| Surface glass rate | ％ | ≥95 |
| Refractoriness | ℃ | 1208-1360 |
| Use temperature | ℃ | 800 |
The comprehensive above index that detects can learn that the cylindrical compress strength of glass bead is higher, process detects the ultimate compression strength of this mortar greater than 1.2MPa, and tensile strength is greater than 0.3MPa, and cohesive strength is greater than 0.3MPa, therefore, intensity morning of this mortar is very high, helps construction; Thermal conductivity is little, only is 0.028-0.05w/m.k, is suitable as very much the material of building heat preservation; Weather resisteant is good, because glass microballon is to make through high temperature, and glassiness mineral material can be high temperature resistant 800 ℃, and its resistance to deterioration is good; Environmental protection makes through the high temperature of 1208-1360, so it does not have the radioactive nuleus essence, is a kind of construction timber of green.The present invention adopts the glass bead mixed mortar; be mainly used in the inside and outside volume recombination insulation of building; guaranteed the stability of quality product; its good combination property; early strength improves fast, significantly is better than the thermal insulation mortar that granular polystyrene is an aglite, has shortened secondary and has plastered the time; improve operating efficiency greatly, reduce engineering cost.
As mentioned above, only be preferred embodiment of the present invention, can not limit the present invention's interest field with this, therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
